Benji synrod air pressure/hammer spring adjusting advice

[Jedediah]

I recently purchased a 4500 psi fill set up and now want to tune my synrod to accept 3000 psi but can't find my owners manual because I put it "somewhere safe so I wouldn't lose it" so now I'm looking for some advice or instruction on the matter any I site is appreciated thanks
